# Bastion

SSH bastion that features transparent connection and session recording.

This project is inspired by https://github.com/moul/sshportal. I wrote this implementation to work around the fact that I couldn't get the go ssh lib
to work properly with non interactive sessions, the bug has been open for a long time and I tend to belive it cannot be fixed
(https://github.com/moul/sshportal/issues/55).

This bastion project does work properly with non interactive sessions, which allows transparent ansible usage through the bastion.

## Dependencies

This project has only one hard dependency :
- the libssh from https://www.libssh.org/. You should be able to use your distro's packages if they are recent enough.

The following are optional dependencies :
- the libtty from https://github.com/kilobyte/termrec which allows session recording.
- compression libraries like libbz2, liblzma, libz allow on the fly compression of session records.
- libmysql for now because it hosts the runtime config

## Manual Installation

This project is built using cmake :
```
mkdir build
cd build
cmake ..
make
make install
```

You can customise the build with the following cmake flags :

- `CMAKE_BUILD_TYPE` : Debug|Release|RelWithDebInfo|MinSizeRel, defaults to Release
- `CMAKE_INSTALL_PREFIX` : path, defaults to `/usr/local`
- `SESSION_RECORDING` : ON|OFF, defaults to ON

For exemple this disables session recording for a debug build and installs the bastion for your current user :

`cmake .. -DCMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=$HOME/.local -DSESSION_RECORDING=OFF`
